SHINGLE-STRAPPING- SUPPORT.

Application led July 15, 1921. Serial No. 484,904.

concern:

I, RICHARD D. LIVING- izen of the United States, and Chicago, in the county of Cook have invented a cerand useful Improvement in of which the concise, and exact reference being had to the acforming a part of this specification.

My invention relates to improvements 1n means .for

applying bails to packages, and

is particularly concerned with the provision of novel means for applying hails to packages where itis desired to apply a plurality of bands to a package,

bands pass direction,

either where the around the package in the same or in directions at an angle to each other.

The objects of my invention are:

First: To provide means for expenditing and facilitating the application of bands to packages of all kinds.

Second and easily a package To provide means for quickly applying aplurality of bands to where said bands are applied to the package In spaced relation, or in directions at an angle to each other.

Third porting a parallel with To provide novel means for suppackage with its binding axis the axis of a coil of .strapor other binding material so that the strap can be easily transferred from the coil to a position about the package.

Fourth t ter describ easily and To provide means of the characed, whereby the package can be quickly moved to bring a new part of the package into the proper relation to the coil supporting means bail.

Fifth packages to be to receive a To `provide a novel support for bound, which will provide ort for the package, and, at the permit the package to he bound without the necessity of lifting it for the passage thereabouts Sixth a package,

easily and bound.

Seventh of the bail.

To provide a novel support for from which the package can be quickly removed after being To provide means for supporting a package while being bound, comprising a mem age during ber which is bound t the packthe binding operation, but which is of such shape and dimensions as to permit the package to be withdrawn from it without materially affecting the tensioning of the bail, and

Eighth: To provide means which is particularly adapted for strapping objects such as shingles, panels, plaster board,V and other similar objects, into bundles.

Other objects will appear as this description progresses, reference being had to the accompanyingdrawings, in which Figure 1 is a side elevation, partly in cross section, of a strapping stand forming a art of my invention, which I have here iustrated asbeing used for forming and strapping a bundle of shingles;

Figure 10 is a side elevation showin a still further modified form of strapplng stand in combination with a frame or support for holding a coil of binding material with the axis thereof substantially parallel with the strapping-axis of the package to be bound, and

Figure 11 is a plan view of the construction shown in Figure 10.

Referring Vfor the present to Figures 1 to 5 inclusive, in which I have illustrated my improved strapping stand used for the purpose of applying bands to a bundle of shingles or other similar objects, I provide a table 1, upon the arm 2, pivotally mounted on holt' 3 in the stand 4. The table 1 is in the form of a rectangular oblong (for supporting a corner of the pile) from which projects a diagonal extension (for supporting the rest of the pile). The plates 5, attached to the two outer margins of the table, serve to square the edges of the pile at one corner, and the elongated thin volv metal extension 6, projecting diagonally from the opposite corner completes the support for the pile. Thus, a pile of shingles 7 may be stacked on the' tabl'e 1, and extension 6. and squared by the corner plates 5. Stacking is facilitated by the slight inclination of the table and corner plates as shown in Figure 1.

yI shall now describe thestrap guiding means. Between the edges of the extension 6 and the adjacent corners pf the table are depending vertical flanges 8, which may be secured to the table by screws 9 or by other suitable means. As shown in Figs. 1 and 2, when a pile of shingles is on the table, the plates 8' will each lie approximately at the center of the pile. A tensional binder 10 can then very quickly be applied about the center of the pile of shingles, which is entirely exposed except for the thin plate 6 around which the binder is put, as shown in Fig. 1. The flanges 8 serve as an accurate guide for the strap. In other words, the strap, while being wrapped about the pile, is pushed sideways up against the one or other of the flanges 8, which insures its proper position at the center of thepile, after which it is tightened and a joint 11 formed in the ordinary way.

For convenience in operation, I have mounted the table 1 pivotally upon the standard 4 and have provided the bolt 12, working in the quadrant recess 13 in the head 14 of the stand 4. By this means the table 1 may be revolvedninety degrees so as to bring the pile with its long or short side respectively directly in front'of an operator and to permit the application of the two binders with equal facility in a manner clearly illustrated in Figs. 2 and 3. It will be observed that the arm 2 which supports the table, extends, not only upwardly, to afford a clearance over the top of the stand, but also outwardly. This offsets the table so that either of its two inner edges is aligned with the axis of revolution, and the strapping operation is carried out in the same (plane, for both straps, the table being turne ninety degrees as described.

For further convenience I have mounted the standard 4 within the standard 15, secured upon a base 16, and have provided the holes 17 through which projects the pin 18, projecting also through aligned apertures in the standard 15. By this means, the table 1 may be adj usted in height. A set screw 19 prevents play of the standard 4 in the standard 15.

In operation, the ile of shingles is quickly placed u on the ta le 1 and squared up against t e corner plates 5. After this with the table 1 in the position shown in Fig. 2', a binder 10 is applied, the flange 8 serving as a eguide; immediately the table 1 is reninety degrees bringing the parts in the position Fig. 3, whereupon the other strap 10 is applied in the same way.v The completed bundle is pulled outwardly along and off Vthe thin extension 6, the whole operation being performed in a very few seconds. It will be observed that the table 1 is within an area of the bundle not covered by strap,

ydetrimentally affecting the tension of the bands or binders, by reason of the inclusion of the extension 6 with the bundle during the binding operation.

In Figs. 6 to 9 inclusive, I have illustrated a modified ,form of my strapping stand in which I provide a table 21, preferably formed of wood, the upper surface 'of which is covered with a heavy sheet metal plate 22, the rear portionl of which is bent upwardly at a right angle to the table 21 to provide a back yplate 23, and one end of which projects from the end of the table 21 to provide an extension 24 for supporting one end of the package to be bound. For the purpose of strengthening the extension 24 against bending stresses, I prefer to p-rovide the plate 22 with a longitudinally extending corrugation 25. This corrugation tapers in depth from a maximum depth at a point adjacent the table 21 to practically nothing at lthe outer end of the extension. The maximum depth of the corrugation should not be suflicient to ymaterially affect the tension of the band or binder when the package is removed from the stand. A guide bar 26 extends downwardly from each side of each end of the table 21 to provide means for guiding the ystrap or other ybinding material into the proper position on the package. Y

For the purpose of' rotatably supporting -the table 21' and the parts attached thereto,

I provide a stand comprising 'a base 27 which supports a standard 28, the upper end of which is secured to the head 29. A plate 3() is rotatably mounted upon the head 29 and is pivotally held thereon by means of thel bolt 31 which extends upwardly through the head 29 and a suitable opening in the Iplate 30. Nuts 32 at the upper end of the olt 31 prevent the table from being lifted from the stand. The plate 30 is provided with a plurality of upwardly extending bosses 33 to which the table and its sheet metal cover 22 are secured by means of the screws 34. At 35 and 36 I have illustrated a discontinuous duct passin throu h the table 21 and the plate 30 or con ucting lubricant to the upper surface of the head 29.

In using the strapping stand described above, the box, package, or stack of material to be bound is placed upon the stand 1n the position indicated in dotted outline in Fig- .ure 8.

A strap 37 is then placed around the package at substantially its middle point. This strap Will, of course, include the extension 24 with the package. Another strap 38 is then placed around the package adjacent to the end of the extension 24` or, if necessary, placed around the bundle to include this extension. The table 21 is then rotated 1800 upon 'its axis, and the strap 39 applied to the other end of the package or bundle. The package can then be Withdrawn from the stand in a. left hand direction (Fig. 9). Similar to the extension 6 shown in Figs. 1 to 4 inclusive, the extension 24 shown in Figs. 6 to 9 inclusive is in such shape and such dimension that its inclusion in a package does not materially affect the tension of the band or binder when the package is removed from the strapping stand.

It Will be-noted that in the modified form of my invention shown in Figs. 6 to 9 inclusive, the pivotal support is not at the longitudinal center of the table 21. but is located relatively near. one end of this table, this being for the purpose of bringing the pivotal support'at substantially the center of the package to be bound.

In Figs. 1() and 11, I have illustrated my complete invention in which the strapping stand forming a part that shown in Figs. 6 to 9 inclusive. except that the extension 24 shown` in the last mentioned figures is omitted, and the pivotal support for the table 21 is positioned substantially centrally of the table. In Figs. 10 and 11, I have shown in combination with the strapping stand a frame for sup-- porting a coil 40 of strap, or other suitable binding material, in a substantially vertical position, this frame comprising the two side members. 41, cross member 42, to which are secured the backing bars 43. TWO braces 44 prevent the supporting frame from tipping over. An arm 45 is secured to the backing bars 43 in such manner that it projects outwardly through the coil. The outer end ,of the arm 45 is provided With a clip 4G for holding the free end of the strap when it is not being manipulated about a package. If desired. the coil supporting frame and the strapping stand may be secured to the same platform 47.

In the use of the apparatus illustrated in Figs. 10 and 11, a plurality of convulsions 48 can 'be transferred from the coil 40 to the arm 45, Where they will be within easy reaching distance of the operator. The operator can then, by a single movement, transfer a convolution of the coil' 40 to a positionl about one end of the package.

thereof is similar to- The overlapping positions of the strap can then be secured by a suitable seal 50, and the free portion ot' the strap broken or otherwise severed from the band and secured under the clip 46. The support and package is then rotated to bring the opposite end of the package into the proper position relative to the coil 40 to receive another convolution or portion of a convolution of the coil 40 and the operation of securing the strap to the package repeated.

lVhile I have described the coil supporting Jframe only in connection with the strapping stand illustrated in Figs. 10 and 11, it is to be clearly understood that it can be similarly used in connection with the strapping stands illustrated in the remaining Iigures of the drawings, and that I have not illustrated suchuse merely for the purpose of saving illustration. Thestrapping stands which I have illustrated can, how'- ever, be used to goodl advantage Without a coil supporting stand.

While I have described the details of construction of the preferred embodiment of my invention, it is to be clearly understood that my invention is not limited to these de. tails of construction. but is capable of other adaptations and modifications Within the scope of the appended claims.
